Cascadeur

Cascadeur is a physics-based 3D animation app with AI AutoPosing that helps animators create lifelike character motion with fewer manual keyframes.

Cascadeur is a desktop animation tool built around the idea of physically plausible motion. Instead of relying purely on manual keyframing, it offers AI-driven AutoPosing (predicting a natural full-body pose from a few control points), physics-based correction, and tools that help balance, weight and secondary motion feel believable. Animators retain keyframe-level control, so it complements rather than replaces traditional workflows. The software is popular with game studios, indie developers and animators who need combat, action and character motion without a full motion-capture pipeline. It exports to standard formats and integrates with engines like Unreal and tools like Maya and Blender, and it runs on Windows, macOS and Linux. Cascadeur, developed by Nekki, offers a free tier for hobbyists plus Indie and Pro subscriptions. Its physics-first approach is distinctive among AI animation tools, though it has a learning curve and is aimed at users comfortable with 3D animation concepts.
